This bulletin appraises major technological changes emerging in five American industries (coal mining, oil and gas extraction, petroleum refining, petroleum pipeline transportation, and electric and gas utilities) and discusses the impact of these changes on productivity and occupations over the next five to ten years. Its separate reports on each of these energy industries outline (1) recent technological advances, (2) the output and productivity outlook, (3) investment in the industry including capital expenditure and research and development programs, and (4) employment and occupational trends and the adjustment of workers to technological change. The first report discusses environmental and health concerns which have led to a decline in productivity and employment in the coal industry. The need for new oil and gas sources and for more professional and technical workers is covered in the next report on oil and gas extraction refining. Predictions for declines in employment and output in petroleum refining and petroleum pipeline transportation are made in the third and fourth reports. Increasing productivity and employment and changing occupational requirements for electric and gas utilities are outlined in the final report. (MN)
